Mathieu Lirzin commented on OFBIZ-10966:
----------------------------------------
Hello Jayansh,
I have tried your patch and noticed the nice improvements you made in
particular with the addition of tests.
When running the unit test fails on my machine I get the following error:
{code}
> Task :test
org.apache.ofbiz.entity.util.EntityJsonReaderTests > parse FAILED
java.io.IOException at EntityJsonReaderTests.java:82
Caused by: java.lang.reflect.InvocationTargetException at
EntityJsonReaderTests.java:82
Caused by: java.io.IOException at EntityJsonReaderTests.java:82
Caused by: java.lang.NullPointerException at
EntityJsonReaderTests.java:82
{code}
and after trying to rapidly debug, I noticed that you used Java reflection
which should be avoided because it makes things complex and brittle. There are
multiple solutions to avoid that but a flexible one is to use a map associating
strings to method references.
Are you able to reproduce the unit test failure? Can you rework your code to
not use reflection ?
Thanks in advance, and sorry for the long delay.
Note: I will proceed the revert of you initial version I intended to do last
month.
> JSON entity data import and export utility

> Project: OFBiz
> Issue Type: New Feature
> Components: framework
> Reporter: Jayansh Shinde
> Assignee: Mathieu Lirzin
> Priority: Minor
> Fix For: Upcoming Branch

> Currently, we support import/export entity data in XML format.
> Nowadays JSON is widely used in industry, we can have support for JSON
> format which looks quite similar to XML support.
> Here is example of XML data and it's JSON version
> {code:java}
> <Party partyId="123456" partyTypeId="PERSON" statusId="PARTY_ENABLED"/>
> {code}
> {code:java}
> {“Party”:
> {"partyId":"123456","partyTypeId":"PERSON","statusId":"PARTY_ENABLED”}}
> {code}
>
> *Design Proposal*
> We can write *entityImportJson* and *entityImportDirJson* services for
> importing JSON from screen and directory respectively.
> And the *entityExportAllJson* service for exporting entity data in JSON.
>
> *Import Design*
> The import service will perform following operations:
> 1.) Validate the input JSON data (I am in process of exploring the way for
> this)
> 2.) On successful validation, convert JSON to OFBiz's entity model
> (GenericValue)
> 3.) The GenericValue will be inserted in database by some handler class for
> e.g we can write JsonDataHandler, it will convert given JSON to
> List<GenericValue>, and finally write it to database (Similar pattern is used
> in XML import).
>
> *Export Design*
> Based on existing XML pattern the writeXmlText method of GenericEntity class
> write the exported data in XML format.
> In the similar way, we can implement writeJsonText to export data in JSON
> format.
> Please free feel to share your thought.
